GAS-PRESSURE PUMP.

SPECIFICATION forming part of Letters Patent No. 406,261, dated July 2, 1889.

Application filed June 23, 1888. Serial No. 277,997. (No model.)

To all whom t may concern.-

Be it known that we, VILLIAM H. OASTOR and SAMUEL B. OASTOR, citizens of the United States, residing in Wayne township, in the county of Hamilton and State of Indiana, have invented certain 'new and useful Improvements in Gas-Pressure Pumps, of which the following is a specification.

The object of our said invention is to provide a cheap and efcient means for elevat.

ing water or other substances by means of natural-gas pressure, as will be hereinafter particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a side elevation of the apparatus We have devised for this purpose, shown in its operative position in a well; Fig. 2, a central vertical section through a portion of the apparatus, the central portion of which is broken out to enable the parts to be illustrated on a larger scale; Fig. 3, a crosssection on the dotted line 3 3 in Fig. 2; and Fig. 4, a View similar to Fig. 2, showing a modified construction adapted for use with driven wells.

In the accompanying drawings, the portion marked A represents the main body or stock of the pump, and B the gas-supply pipe.

The pump-stock A is preferably a metallic tube, as shown, arranged in the well in the usual manner, and provided on its top with a discharge-spout and on its lower end with a collar provided vwith a series of tubular setscrews c, extending in toward its center for securing the gas-pipe in position and affording inlet-openings for the water, as will be presently described.

The gas-supply pipe B is any suitable pipe connected with the gas-main, or other source of supply, by a connecting-pipe B', and is provided with a valve b in its upper end in a convenient position to be operated for controlling the supply of the gas. It is extended down into the well alongside the pump-stock to the lower end thereof, where it is turned and extended up into said pump-stock a considerable distance, its upper end being beneath the surface of the water.

It is considerably smaller than the pump-stock pipe, and is secured centrally therein by means of the tubular set-screws a., which are screwed in against said gas-pipe, and thus secure it rigidly in position. A valve B2, consisting, pref erably, of a small rod provided with a cap with suitable packing on its under side, is mounted in the upper end of the gas-pipe, and operates to close said upper end when the apparatus is not in use, as will be presently described. A cross-pin or other suitable device a is mounted within the pump-stock a short distance above this valve to prevent it from being thrown out by the force of the gas.

The operation of our invention is as follows: It is first placed in the position in the well, asrshown, the gas-pipe being suitably connected with the gas-supply, when it is ready for immediate use. It being desired to put the apparatus in operation, the gas is turned on by means of the valve b, and rushes through said pipe to the top end within the pump, forcing the valve B2 off its seat, which permits said gas to escape into the water or other substances which are within the pump-stock above this point. The force of the gas operates to carry the water or other substance upward to the top lof the stock and out together with the gas, which passes upward when escaping, and may be carried off into pipes for use, if desired, while the Water falls into the receptacle provided. This operation creates the suction necessary to draw in a supply of water from the well through the tubular set-screws cl., and the annular opening in the lower end of the pump-stock around the gas-pipe, thus maintaining a continual steady stream of water from the discharge-spout as long as the gas is permitted to flow into the pump. When the supply of water desired has been secured, the valve b is operated to cut oif the supply of gas, when the weight of thewater above the valve B2 carries it down to its seat on the upperend of the gas-pipe B, forming a tight joint and preventing any further escape of gas, or any water from getting into said gas-pipe.

The construction shown in Fig. .tis for use with driven wells, in which case it is impos- IOO sible, on aeeount of the size of the well, to have the gas-pipe extended down on the outside of the tubing. As shown, the gas-pipe is extended into the tubing at the top of the well and down to near the bottom, where its end is mounted in a Valve Consisting' of a short pieee of tubing of a larger size, which is provided with a cap, and is secured thereto by a spring, one end of which is attaehed to said Valve and the other to the gas-pipe, and operates to hold said valve,whieh is provided with suitable packing against the lower end of said gas-pipe. The operation of the gas forces the valve away from the end of the gas-pipe, stretching the spring suiiieiently t0 permit the gas to escape 'from its lower end through perforations in the lower end of the valve, and also up through the annular space between the valve and gas-pipe, operating to elevate the water in the saine manner as with the other forni of pulnp, as will be readily understood.

Having thus fully deseribed our said invention, what we elaiin as new, and desire to seeure by Letters Patent, is-

1. The apparat-us for elevating water or a similar substance, consist-ing of a pipe inserted in a supply of water and another pipe arranged within said iirst pipe for supplyin gas under pressure, its top end being arranged beneath the surface of the water or other substance, and the tubular set-screw a, inserted through said iirstinentio11ed pipe against said last-mentioned pipe, whereby it is seeured in position and water-inlets provided, substantially as set forth.

2. The combination, in an apparatus for ele vating water, of the pipe A, the lower end ol. which is inserted in the water-supply, the natural-gas pipe B, inserted in the lower end of said pipe A, and the valve B2 in the upper end of said pipe B, Consisting of a disk of a size to elose the end of said pipe mounted on a stein which extends down into said pipe, and the stop a', arranged above said Valve in the pipe A, all substantially as described, and for the purpose speeiiied.

3. The Combination of a pipe or stoel( A, extending' beneath the surface of the water or other substance to be elevated, the gas-pipe B, provided with a valve l), and extending up into the lower end of the stoel: or pipe A, and the valve B2, arranged in the top of said pipe B, subject to gas-pressure on the lower side "and water-pressure on the upper side, suitable openings being provided at the lower end of the stock Or pipe A for the inflow of the substance to be elevated, substantially set forth.

In witness whereof we have hereunto set our hands and seals at Indianapolis, Indiana,

this 19th day of June, A. D. 1888.
